Coronectomy as an alternative technique to the extraction of impacted third molars with risk of injury to the inferior alveolar nerve

Abstract

sciELO, using the DeCS "coronectomy", "odontectomy", "trigeminal", "nerve damage", respecting the criterion of relevance to the topic, 31 articles were selected. It is known that the inferior alveolar nerve passes through the mandibular canal and is responsible for the sensitive innervation of important anatomical structures, so impacted teeth that are very close to the mandibular canal when extraction techniques are used has the risk of injuring the nerve, which may lead to temporary or permanent loss of sensitivity, the indication for performing the technique needs to be made after the radiographic and tomographic analysis of the affinity between the tooth and the mandibular canal. The technique consists of removing the crown of the tooth and enough of the root below the buccal and lingual crest of the bone, so that it can trigger a natural healing process on the retained roots. It is concluded that coronectomy is a safe and effective alternative procedure for specific cases that are indicated and have a favorable prognosis.
